The British Belief for Ornithology started off tagging cuckoos in 2011 to recognize why we’ve lost around fifty percent the amount of cuckoos in the British isles around the previous 20 decades. 

The tags have uncovered heaps of crucial data, these as  how the diverse routes taken are joined to declines, and some of the pressures they encounter even though on migration.

BTO is now wanting additional closely at how dependent they are on, and how a great deal their migration is linked, to the drought-busting rains of the climate frontal program regarded as the Inter Tropical Convergence Zone (ITCZ) as they move out of the Congo rainforest and start out to head back again to the British isles by using West Africa.

Cuckoos, swallows, household martins and swifts are amid dozens of species which devote summer here to lay eggs and rear their youthful, but migrate to Africa for the winter season.

We have lost around two-thirds of our breeding cuckoos in the Uk as a full and pretty much 3-quarters of them in England through the past 23 several years, in accordance to the team.

Dr Chris Hewson, lead scientist on the BTO project, claimed: ‘We have been avidly monitoring PJ considering the fact that he commenced his journey back again to the United kingdom from Africa in late February, prepared him to total the journey.

‘We can now heave a substantial sigh of reduction knowing he is properly again in Suffolk but of program, much more than that I appear forward to seeking much more closely at the information and facts he has specified us.

Once a cuckoo has been fitted with a satellite tag and unveiled it begins delivering data straight absent, permitting scientists to ascertain how effectively the birds fare no subject where they go.

Anyone can comply with them via the BTO web page in in close proximity to serious time.

This spring. the BTO will be tagging 12 far more cuckoos and you can abide by them at www.bto.org/cuckoos.
